The PC-B25S is a recent addition to Lian Li's extensive aluminum PC tower case lineup. Along with Cooler Master and Silverstone, Lian Li has been long associated with aluminum PC cases, especially high end models. The PC-B25S is not at the top of the Lian Li catalog, but it is not at the bottom, either. Any case that carries a >$200 price tag certainly has to go beyond the essentials. Mid Tower, it is called, but the generic description belies the number of special features in this case. As the photo below confirms, Silent is a strongly emphasized benefit on the full color carton, along with Noise Reduction Foam.

So we know that the case is pre-lined with some type of acoustic foam on inside panels, but is there more? Yes, a lot more. The PC-B25S has an enormous number of extras and features aimed at noise-conscious PC users. Our review will show that some of these features are ingenious and very well executed, some are smart but don't work quite as intended, and still others don't even make any sense or appear to be absurd errors. There's more than a little sense of being rushed, of a product built with a check list rather than a complete integrated system perspective. Still, it is not without charm, there is some great workmanship and materials, and it works better than you might expect from the previous words in this paragraph.

Low noise is emphasized in the PC-B25S packaging.

The PC-B25S is attractively "skinned" in black brushed aluminum around good "bones". The case at its
tallest point is nearly 21.5", with a depth of 19.25" and width of 8.25", which puts it on the larger side of "mid tower" cases, along with the Antec P183, the Fractal Design Define R2, and the Silverstone Fortress FT01. Its top and front edges are complexly bevelled, but the entire case is formed of aluminum, with virtually no plastics.

Metallic silver feet and the blue ring in front (which lights up when the system is powered on) are the only exceptions to the brushed black anodized aluminum on four sides.

As you can guess from the profile of the top panel, there is a fan atop near the back panel, in addition to a back panel exhaust fan. Before we go further, here are the complete specifications from Lian Li.
